I have encountered some websites that when I used
-- to comment the rest of the query it didn't work, but when I tried
--+ it worked.
In the MySQL official documentation there is no such thing as
--+ and we only have
-- and two other ways.
Why does this happen (in detail)? I want to know exactly why this works sometimes and
-- doesn't, and why there is no
--+ for comments in the MySQL man page?
